Standardization activities at the WiMAX Forum

To promote the use of WiMAX technology for mobile devices, KDDI has since 2005 been taking part in the WiMAX Forum, established in 2001 for the purpose of applying this technology to fixed communications. The company has contributed to realizing mobile WiMAX by collaborating with Sprint Nextel and other communications carriers in various countries.

Today, the WiMAX Forum has over 500 corporate members including communications equipment vendors and communications carriers, and has become an internationally influential organization for promoting standardization. In recognition of KDDI's vigorous leadership and standardization activities, the Forum selected KDDI executive director Hideo Okinaka in July 2006 as a board member, and made KDDI the only Japanese communications carrier to receive this honor. Since then, in addition to conventional technological activities, KDDI has taken part in the Forum's decision-making processes as one of the fifteen board member corporations, and contributed to promoting the global spread and development of WiMAX.

KDDI has also actively carried out programs aimed at encouraging the growth and development of WiMAX technology in Japan. For example, it has led the Forum's activities to help make WiMAX standards comply with Japan's wireless standards environment , and to ensure WiMAX-compatible terminals manufactured all over the world are also freely available for use in Japan. Through these achievements, KDDI has contributed to the development and expansion of Japan's communications industry as well.

At the IEEE 802.16 Committee that determines WiMAX Forum's standardization specifications, or more specifically, for the Relay Task Group which works to standardize WiMAX as IEEE 802.16e's expanded technology, Mitsuo Nohara of the KDDI Research Institute was appointed chairman of the IEEE-802.16TG. As Japan's first communications carrier to take on this role, KDDI has also contributed to standardization activities at the IEEE.

WiMAX Forum
The official name is the Worldwide Interoperability for Microwave Access Forum.

The Forum was established in 2001, led by Intel and other corporations, with the goal of adopting the technologies approved by The Institute of Electrical and Electronics Engineers, Inc. (IEEE), implementing global-scale dissemination activities and technological discussions, and establishing various specifications. It is a non-profit corporation that tests the compatibility and interoperability of various companies' communications devices for meeting WiMAX installation specifications, and issues authorizations. Over 500 companies currently take part in this Forum.

Overview of Mobile WiMAX's pilot tests

KDDI became the first Japanese company to develop a testing system for mobile WiMAX that meets the IEEE802.16e standard, and began carrying out demonstration experiments in downtown Osaka City from May 2005, aimed at evaluating the system's performance, among other items.
The experiments evaluated the yet-unknown basic performance and functions of the mobile WiMAX system, including communications speed under a mobile environment as well as high-speed handovers between base stations. The tests confirmed mobile WiMAX's high practicality even in an urban environment, and the company released the findings in February 2006 to telecommunications carriers, scientists, and members of the press

In the latter half of 2006, KDDI investigated mobile WiMAX's performance when multiple terminals were used simultaneously, and examined multi-antenna technology (Note) that enhances frequency efficiency. At the same time, it worked to improve a transmitter's distortion properties considered a challenge in broadband wireless communications and to enhance efficiency, and succeeded in attaining the world's highest power efficiency (general power efficiency of 30%), thereby making the base station facilities more compact and energy-efficient.

As seen, KDDI has been performing technological development ahead of all other companies and disclosing information on experiments to arouse Japanese people's interest in mobile WiMAX and to motivate the vendors to carry out development activities. At the same time, it has been aggressively feeding back the results of their experiments to IEEE802.16e standardization activities and to proposals at the WiMAX Forum for establishing installation specifications, thereby contributing greatly to mobile WiMAX's technological development and growth.

(Note) Multi-antenna technologies
Besides the Multi-Input, Multi-Output (MIMO) technology that uses multiple antennae to stabilize or double wireless transmission speed, multi-antenna technologies include beam-forming technology that directs radio wave beams to the desired direction by combining multiple antenna arrays, and spatial multiplexing technology that makes use of this technology.
